Question

Numărul de moli de CO indice 2 aflați în 4kgCO indice 2.

Answer 1

4 kg CO2                   MCO2=12+2.16=44
X moli CO2                44kg CO2---------1kmol CO2
                                    4kg CO2-----------Xk moli CO2
                                  x=4:44=0,090 kmoli CO2=90 moli CO2
                                

Answer 2

CO₂ dioxid de carbon 
CO monoxid de carbon
M CO₂ = 12+ (2*16)= 12+32= 44g/ mol
Numarul de moli  n= m/M
4Kg CO₂= 4000g CO₂
m= 4000g
n= 4000/44= 90,9 moli CO₂
